Yan County Medical No Chang Mountain, which is a mountain range that almost divides Yan County into two. This mountain range is not long and runs north and south, with a mountain range of only more than a hundred miles. However, because Yan County itself is narrow, it is particularly prominent.

In the northern section of Yiwuchang Mountain, it is an endless mountain pasture. It was once the Sui army's horse breeding place during the Battle of Goryeo. The horse farm was dozens of miles in radius. Although the war had been many years, traces of the horse farm could still be found. Some railings were still vaguely visible, and most of the railings were taken home by the locals as firewood.

The high place is grey rocks and exposed. Large areas of forest are distributed from the mountainside, with green pines and cypresses and thick green. Along the mountains, the forest that stretches for hundreds of miles is like a green belt that wraps the mountains around.

In the early morning, a team of cavalry of about fifty people rushed out of the forest and rushed towards the east. This was a team of Sui army scouts equipped with two horses. The speeding knights were all wearing armor, shining black and shining, and moving rapidly.

Their war horses were tall and powerful, strong and powerful, with well-proportioned limbs, with shiny brown horses, long tails flying in the wind, and high necks were densely covered with brushed manes.

The cavalry and the war horses under their crotch complement each other. Everyone was tall and burly, with long hands and feet. The thick black hair under the eagle-edged helmet was fluttering, with a stern expression and sharp eyes. They held a jujube wood spear in their hands, with cowhide shields and bows and arrows on their backs. There was a horizontal knife on the belt. The shiny armor was very strong.

Fifty cavalrymen walked in a two-man column, followed by another horse of theirs, carrying their blankets and dry food, and were young and brave, only sixteen or seventeen years old. His bright eyes were shining with a mature light that was not matched by his age.

The captain was Xiao Yannian. He held the phoenix-winged bells made by his father in his hand and rode a very majestic white war horse. This war horse was tributed to the court in the Western Regions and was rewarded by Yang Guang to his father Yuwen Chengdu. Even his armor was left to him by his father.

Although Xiao Yannian was full of his father's imprint, it was just his memorial to his father. He did not become arrogant because of his father.

On the contrary, he was very low-key. None of his fifty subordinates knew that he was the son of Yuwen Chengdu, the general of the left guard of the Sui Dynasty. However, he was a lieutenant at such a young age, which still made some veterans dissatisfied, which was not in line with the custom of the Sui army's promotion with military merits.

The cavalry team ran for more than two hours. Gradually slowed down, and there was another dense forest ahead. Xiao Yannian pointed at the horse whip and said, "Go to the forest to rest!"

The cavalry turned their horses, crossed a stream, and rushed into the forest. The forest covers hundreds of acres of land, deep and quiet. The ground is covered with colorful flowers, and the roots are covered with white fungi. It can be seen that there is no trace of people here.

The soldiers dismounted and sat down on the grass. More than a dozen soldiers took gourds and buckets to fetch water from the stream outside, and the war horses leisurely ate the grass on the grass.

Xiao Yannian sat next to a flat rock to view the map. His serious eyes looked very much like his father, and his tall nose showed his noble bloodline of the Southern Dynasty nobles.

This time, he was ordered by Luo Shixin to investigate the movements of the Goryeo Army. He quickly found his current seat on the map and drew a circle on the map with a piece of charcoal. This was located twenty miles north of Huaiyuan Town, and ten miles eastwards were the Liaohe River.

He patrolled the area for almost seven days. He still did not see any trace of the Goryeo Army, but only found a Yan army with thousands of people the day before yesterday.

‘Does I have to cross the Liaohe River?’ Xiao Yannian thought to himself.

At this time, a team was approaching him and said with a smile: "Captain, why not find a village, some eat, some drink, and even find out the news."

Xiao Yannian glanced at him, "This is the territory of Gaokaidao. We should not be too arrogant, otherwise we will be informed by the villagers and will not know how they die. More importantly, it will miss the general's major event."

"But, will there really be a Goryeo army?"

The team was hesitating for a while, and finally couldn't help saying: "Brothers say that it is unlikely to encounter the Goryeo army. We have been patrolling Yan County for seven days. If we could meet it, we should have encountered it long ago. We all think that even if we search for it for ten days, there will be no news. It's better... than to go home just by going home, right?"

Xiao Yannian snorted coldly and said, "I know when it will end, so I don't need you to remind me!"

The team looked very embarrassed and had to laugh dryly, "I just talk about it casually, of course it was the lieutenant who decided."

The team was retreating and sat down against the tree roots. He cursed quietly. Several veterans immediately surrounded him and asked in a low voice: "What do you mean, will the lieutenant continue to patrol?"

"Get away!"

The team was cursing, "It was all you guys who were troublesome, which made me scolded."

Several veterans refused to leave, gathered beside the team, and talked angrily: "Who is this lieutenant? He was inexplicably the lieutenant. What is his background?"

"Who knows? I guess it's a big deal. I heard that the general manager had competed with him when he inspected Hedong County. His surname was Xiao, and I guess he was a nobleman from Xiliang."

Team Master sighed, "No matter who it is, one thing is certain that he will be promoted faster than us. Anyway, when you were a team leader, he was at least an Asian general, so the best way is to be honest and obedient and not provoke him."

The veterans were confused, but they had to listen to the team's right words. At this moment, the soldiers watching from the top of the big tree shouted: "Several cavalry are running towards us!"

The soldiers jumped up one after another, and Xiao Yannian ordered: "Don't panic, retreat deep into the forest!"

The soldiers quickly packed up their things, led the horses, and retreated into the depths of the forest. Xiao Yannian led more than a dozen scouts to ambush the nearby trees.

After a moment, three cavalrymen rushed into the forest, all of them were Gao Kaidao's soldiers. As soon as they entered the forest, one of them started to curse, "Take me like a dog, I quit. Dog shit, Korean people, if you have the ability, they will send their own people to deliver letters."

At this time, another soldier suddenly discovered an abnormality, "No, someone has been here, and some cavalry have come."

They found the feces of horses and war horses. The three Yan soldiers immediately realized something was wrong and turned around to run out of the forest. At this moment, several arrows shot towards them, all of which were shot on their legs. The three of them fell to the ground with screams, jumped off the tree, and held them with their spears.

"Give me your life!"

The Yan army spy shouted loudly in horror. Xiao Yannian quickly stepped forward, grabbed a man's hair, dragged him under a big tree, squatted down and asked, "Where is the Goryeo Army?"

The spy was so scared that he was trembling all over and couldn't say a word. Xiao Yannian pulled out a dagger to press against his throat, "Speak quickly, or you will be killed with one knife."

"On the east bank of the Liao River!" The spy said tremblingly, tremblingly.

"How many troops are there, when will it be to cross the Liaohe River, and who is the chief general?"

Xiao Yannian asked a series of questions... Liaohe River, which was once the boundary river between Goryeo and the Sui Dynasty, was also the first step in the Goryeo War that year. It was the frontier position for the Great Sui Dynasty to attack Goryeo. Although the war had ended for many years, there were still no people living on both sides of the Liaohe River. There were too many people dead here, and the land was full of death.

On the banks of the Liaodong River, the city occupied by hundreds of thousands of people in the Sui army that died in battle has been occupied by the Goryeo people again. Now a Liao River can no longer stop the ambition of the Goryeo people. They took advantage of the opportunity of Gaokaidao to surrender and began to expand westward.

The Liao River is about tens of feet wide and the water is deep and flat. At this time, two floating bridges have been built on the Liao River. Teams of Goryeo soldiers are quickly crossing the floating bridge and heading towards the west bank of the river. On the east bank of the river, tens of thousands of troops are arranged in a dense manner, with a huge momentum.

Although Gai Suwen and Gao Kaidao negotiated that 30,000 troops were sent, in the final decision, Yuan Taizuo, the prime minister of Goryeo, who held military and political power, changed his mind. He thought it would be difficult for 30,000 troops to defeat the Sui army, so he decided to send 50,000 troops, led by him personally to fight the Sui army.

On the bank of the Liao River, Yuan Taizuo stared at the Liao River in a cold look. On this river, six years ago, the Sui army launched a large-scale attack on Goryeo. Three consecutive battles almost destroyed Goryeo's foundation. Now, six years later, it is his Goryeo army attacking the Sui Dynasty, no! It is attacking the Central Plains.

Yuan Taizuo has been waiting for this moment for a long time, and this has always been his dream. He is sixty years old this year. He thought he would no longer have a chance in this life, but he did not expect that in his twilight years, this moment would become true. He was so excited that he decided to lead the army to the west in person to realize his decades of long-term wish.

"Father!"

The eldest son Gai Suwen rushed from a distance. This time, the Goryeo Army fought westward, but stayed in Goryeo and took charge of military affairs for his father. He rushed to the Liao River to see off his father.

"When will my father return this Western Expedition?" Gasuwen asked worriedly.

"I don't know either, it's almost two months, and it's half a year later."

Yuan Taizuo trusted his eldest son very much. He personally led the army to the west and handed over all the military and political power in his hands to him. He smiled and patted his son on the shoulder, "You are already thirty years old. With your talent, I believe you can take on this burden. King Rongliu just succeeded to the throne. He has no prestige yet. As long as you firmly grasp the power, he will have no choice but to do anything to you."

"Please rest assured, I will handle internal affairs well. I hope my father can realize his long-cherished wish as soon as possible."

Yuan Taizuo raised his head and smiled, "Yes! Thinking that the decades of long-standing wish is about to come true, even if I die, I will rest in peace. I will send you good news in Youzhou City."

Yuan Taizuo looked at the wide Liao River. He ordered with great enthusiasm: "With my order, the army will speed up the river... In a dense forest on the other side of the river, Xiao Yannian was leading fifty scouts to watch the Goryeo cross the river closely. The news of Yan army spies confirmed that at least 50,000 Goryeo crossed the Liao River to help fight Gao Kaidao... To be continued)
